Guru Vidhya on Instagram: "This demonstration uses a simple setup to show the concepts of constructive and destructive interference of sound waves. A speaker emits a sound of 800 Hz into a T-shaped pipe (red neck trombone), where the sound wave splits into two paths and then recombines. By changing the length of one path, the distance the sound travels is altered, creating a difference in the path lengths. When this difference equals a whole number multiple of the wavelength (about 43 cm for 800
